pulse oximeter oxygen saturation in prediction of arterial oxygen saturation in liver transplant candidates
results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...
متن کاملDiagnostic Dilemma: Low Oxygen Saturation during Cardiac Surgery
We report a case of rheumatic heart disease with severe mitral stenosis having cyanosis and low oxygen saturation on pulse oximetry. The findings of clinical examination and low values on pulse oximetry were inconsistent with the findings of normal partial pressure of oxygen and oxygen saturation on arterial blood gas analysis, leading to diagnostic dilemma. In such clinical scenario, the anest...
متن کاملEffects of lorazepam on oxygen saturation before cardiac surgery.
We have studied patients presenting for coronary artery bypass surgery on two nights before surgery. Oxygen saturation during a night when the patient received no night sedation was compared with the night before surgery, when lorazepam 3-4 mg was given. There was no difference between the two nights when the total time at oxygen saturations less than 90% were compared, but the minimum oxygen s...
متن کاملMisunderstanding the arterial blood oxygen saturation
Case report An 88-year-old woman was admitted to the emergency department of our hospital with an itchy skin rash that developed while she was on antibiotics (quinolones), administered for an episode of acute cystitis, asthenia and fever. She was suspected to have an allergic reaction and treated with i.v. methylprednisolone 40 mg per day. After 24 hours, skin rash and fever had subsided and th...
متن کاملMeasurements of Cerebral Arterial Oxygen Saturation
This pilot investigation was undertaken to assess the performance of a novel fiber-optic cerebral pulse oximetry system. A fiber-optic probe designed to pass through the lumen of a cranial bolt of the type used to make intracranial pressure measurements was used to obtain optical reflectance signals directly from the brain tissue. Preliminary results from seven patients measured in the operatin...
